摘要:
The invention relates to an arrangement in an industrial robot for driving translatory motion of a unit (7). which in turn is mounted in a gimbal-type suspension having two mutually perpendicular axes (I,II). A motor (9) with associated resolver is mounted in the pivotable frame of the gimbal-type suspension, this frame being capable of being swung in one direction (I), and the motor drives a pinion (10) which meshes with a rack (11) via a shaft (5) which also constitutes the one journal means of the machine part (4) in which the translatorily movable machine part is movably arranged. To this end the shaft (5) is rotatably journalled to both the frame (1) and the machine part (4) through each of its bearings (19,20).

Method of rendering slag-bath reactions more efficient, for example in connection with sulphur removal from steel melts and arrangement for carrying out the method, with stirring of the melt by means of at least one inductive stirrer. According to the invention the stirring is carried out in such a way that the vector for the stirring force is composed of horizontal and vertical components.

Method and casting plant for the production of metal castings in which the molten metal is fed from a heated container (1) to a mould (3) or to a smaller container via a pressure pipe (4), a pressure-generating means (2) and a suction pipe (5). According to the invention the temperature of the metal present in the pressure-generating means (2) is controlled by a heat-generating means (11) in order to maintain the metal at a temperature corresponding to or exceeding its melting point. The metal is present in molten state during its passage through the pressure-generating means (2) and the pipe system. A protective medium is brought to surround at least the pressure-generating means (2) to protect the same during operation and during a downtime period.

Beam of a plastic reinforced with a fibre material, which beam has a curved shape in the longitudinal direction and a cross-section decreasing in the longitudinal direction from the central part towards the ends of the beam. The beam takes particularly the form of a leaf spring. The reinforcement consists of a fibre material (11,12,13,14,15), oriented substantially in the longitudinal direction of the beam, with folded parts (11b,12b,13b,14b) located on both sides of and at different distances from the central part of the beam. Fibre material (12,13,14) which forms a folded part (12b,13b,14b) in the interior ofthe beam surrounds fibre material (11,12,13) which forms those folded parts (11b,12b,13b) in the interior of the beam which are located nearer to the central part of the beam than the folded part of the former mentioned fibre material.

Forming press of the pressure cell type comprising a press stand with two opposed force-absorbing elements (11, 12) between which a space is formed. In this space there is located a plate (20) with a recess in which an elastic diaphragm (22) is arranged. The diaphragm forms, together with the plate, a pressure cell. Elongated side supports (30, 31) for the diaphragm are provided at the sides of the said space. A tray (2) insertable into the space forms, together with the plate and the diaphragm, a closed press space. The pressure cell is connected to a pressure medium source. Each side support is formed with an elongated recess (36), in which there is arranged an expansible member (37) of elastic material. Each expansible member forms a side support for a press tool (45) located in the tray.
